Polycarbonate Plastic Rod PC Rod PC Bar

Product performance

Mechanical properties

High impact strength: Izod notch impact strength ≥600J/m (normal temperature), which is more than 200 times that of ordinary glass and more than 10 times that of PMMA (acrylic). It is known as "bulletproof plastic" and can withstand high-intensity impact without breaking easily. It is suitable for safety protection applications.

Medium rigidity: Tensile strength 50-70MPa, bending modulus 2000-2400MPa, although not as good as metal and some engineering plastics (such as POM, PA), but much higher than ordinary plastics (such as PP, PE), can withstand a certain load without deformation.

High toughness: Elongation at break ≥80%, can undergo large deformation without breaking when subjected to external force, suitable for application scenarios that need to absorb impact energy.

Thermal properties

High heat deformation temperature: heat deformation temperature (under 1.82MPa load) is about 120-140℃, glass transition temperature is about 145-150℃, long-term use temperature range is -40℃ to 120℃ (short-term tolerance is 130℃), suitable for use in high temperature environment.

Low thermal expansion coefficient: about 6.5×10⁻⁵/℃, dimensional stability is better than most plastics, small deformation under temperature change environment, suitable for precision parts.

Optical properties

Excellent transparency: light transmittance can reach 89-92% (close to 92% of ordinary glass), low haze (<1%), small optical distortion, suitable for optical instruments and transparent structural parts.

High refractive index: refractive index is about 1.584, slightly higher than ordinary glass (1.52), can produce special optical effects, suitable for lenses and light guide components.

Chemical properties

Good chemical resistance: It has good resistance to water, seawater, oil, dilute acid (such as dilute hydrochloric acid, dilute sulfuric acid), dilute alkali, etc., and is suitable for general chemical environments.

Limited solvent resistance: It is sensitive to aromatic hydrocarbons (such as benzene, toluene), chlorinated hydrocarbons (such as dichloromethane, carbon tetrachloride) and ketones (such as acetone, methyl ethyl ketone). Long-term contact may cause stress cracking or swelling.

Electrical properties

Excellent insulation: Volume resistivity ≥10¹⁵Ω·cm, dielectric strength 20-30kV/mm, dielectric constant 2.9-3.1 (1MHz), it is an excellent electrical insulation material, suitable for electronic and electrical components.

Processing performance

Easy to process: It can be processed into complex shapes by mechanical processing (turning, milling, drilling), thermoforming (vacuum blister, hot bending), injection molding, etc., and the processing temperature range is 260-320℃.

Easy to bond and coat: The surface can be treated with plasma to improve bonding performance, suitable for surface treatment processes such as spraying and electroplating.

Other features

High specific strength: The specific strength (strength/density ratio) is high, about 8-10 times that of steel and 4-5 times that of aluminum, suitable for lightweight design.

Self-extinguishing: UL94 HB flame retardant grade, no continuous dripping during burning, self-extinguishing after leaving the fire, meeting general flame retardant requirements.

Non-toxic: Meets food contact safety standards (such as FDA, EU 10/2011), and can be used in food processing equipment and medical auxiliary devices.

pc rods

Excellent impact resistance

The impact resistance of PC rods far exceeds that of traditional engineering plastics (such as PA6, POM) and general plastics (such as PP, PE), and even surpasses ordinary glass and acrylic (PMMA), becoming the preferred material for safety protection applications.

Scientific basis for ultra-high impact strength: PC molecular chains contain rigid carbonate groups (-O-CO-O-) and flexible methylene segments. This "rigid and flexible" molecular structure enables it to disperse energy through the movement of molecular segments when impacted by external forces, avoiding rupture caused by stress concentration. Experimental data show that the cantilever beam notch impact strength of PC rods is ≥600J/m (normal temperature), which is more than 10 times that of PMMA and more than 200 times that of ordinary glass. For example, in riot shield applications, protective parts made of PC rods can withstand the impact of high-speed projectiles (such as rubber bullets) without breaking, significantly improving the safety of users.

Retain low-temperature toughness: Traditional plastics (such as PS and PVC) will become brittle in low-temperature environments, and the impact strength will drop sharply, while the brittle temperature of PC bars is as low as below -40°C, and they can still maintain good impact resistance in extremely cold environments. This feature makes it suitable for scenes such as polar scientific research equipment and outdoor safety protection devices in cold areas to avoid material performance degradation caused by temperature changes.

Stability under dynamic loads: In repeated impact or vibration environments (such as protective covers for industrial equipment), the performance degradation rate of PC bars is extremely low (permanent deformation rate <5%), which is much better than ordinary plastics (such as PP, which is prone to cracks under long-term impact). For example, in the application of protective covers for mining machinery, PC bars can withstand the continuous impact of ore splashing, and their service life is 3-5 times longer than that of traditional materials.

polycarbonate rods

Excellent optical transparency

The transmittance and optical stability of PC rods make them an ideal substitute for transparent structural parts, especially in scenes where safety and visibility are required.

High transmittance and low haze: The transmittance of PC rods can reach 89%-92% (close to 92% of ordinary glass), the haze is less than 1%, the optical distortion is small, and it can provide clear, distortion-free visual effects. Compared with PMMA (transmittance of about 92%, but higher haze), PC is less likely to produce a haze on the surface due to scratches or aging while ensuring high transmittance. For example, in the application of lenses in optical instruments, PC rods can replace glass to avoid the risk of shattering due to accidental falls while maintaining excellent optical properties.

High refractive index and special optical effects: The refractive index of PC is about 1.584, slightly higher than that of glass (1.52), and special light refraction or focusing effects can be achieved through optical design. This feature gives it a unique advantage in high-end optical devices (such as laser collimators and fiber couplers), and can improve the transmission efficiency of the optical path.

Scratch and wear resistance: Although the hardness of PC (Rockwell R-scale is about 118) is lower than that of glass (about 550), its surface scratch resistance can be significantly improved through surface coating (such as hard coating) or blending modification (adding nano-silica). For example, in the application of protective covers for security surveillance cameras, the transparent cover made of PC rods not only ensures high-definition image quality, but also avoids wear caused by frequent cleaning.
